INKING APPARATUS FOR PRINTING-MACHINES.

SPECIFICATION formingpart of Letters Patent No. 701,545, dated June 3,1902..-

Application filed November 1,1901. Serial No. 80,722 (No model.)

To ctZZ whom it may concern:

Be it known that 1, CHARLES P. OOTTRELL, a citizen of the United States,and a resident of Westerly, in the county of lVashington and State ofRhode Island, have invented a new and useful Improvement in InkingApparatus for Printing-Machines, of which the following is aspecification.

This invention relates to devices for lifting re and locking what areknown as the rollerstand tops which contain the distributingrollers inthe inking apparatus of printingmachines;.and it further relates todevices through which by the act of raising the said V I 5 stand-topsthe form-rollers are at the same time raised above the forms.

The object of the improvement is to provide greater facility andconvenience for the lifting of the said stand-tops and rollers whennecessary; and to this end the invention consists in the mechanismillustrated by the accompanying drawings and hereinafter described andclaimed.

Figure 1 in the drawings represents a side view of theimpression-cylinder and its inking apparatus and part of the framing ofa printing-machine and of the lifting and looking devices for theink-rollers, showing the several rollers in their operative positions.

Fig. 2 is a plan of part of one of the side frames and the adjacentportions of the impression-cylinder and ink-rollers and of the liftingand locking devices on the corresponding side of the machine; Fig. 3, atransverse 5 elevation corresponding with Fig. 2 Fig. 4c, a side viewshowing the roller-stand tops and rollers all lifted.

Adesignates the main framing, containing the bearings for the journalsof the impreso sion-cylinder B. On each side of this framing is erectedone of the stationary rollerstands C, on which are the bearings a forthe form-rollers Z). Above the said stands C the stand-tops D aredirectly hinged or pivoted 4.5 at fixed points 0 to the main framing,the said stand-tops containingthe bearings for distributing-rollersconsisting of the vibrators d and top riders 6. It will be understoodthat there is one of these stands 0 and tops D for 5:: each side of themachine, and therefore I have fixed stud Z and the gear 70 turns freelyon a fixed stud it, said studs being secured in or on the framing. Byturning or allowing the hand wheel l to turn in one direction or theother the stand-tops D are lifted to the position shown in Fig. 4: orallowed to drop to the position shown in Fig. 1, in which they rest onthe stands C. To provide for locking the tops D down upon the stands, asshown in Fig. 1, there is provided on the gear j a short ratchet 7'which is engaged by a pawl j pivoted to the framing A. The said gearjhas provided upon it a laterally-projecting flange 9', upon which thepawl 7' rests when not engaged with the ratchet-teeth To provide forlocking the tops D in the lifted positions shown in Fig. 4., there is aratchet-wheel m, fast to the hand-wheel Z and pinion Z, and a pawl m ispivoted to the framing to engage with said ratchet-wheel.

On the inner face of each roller-stand there is set up edgewise underthe journals Z) of the corresponding ends of the form-rollers b alifting-plate E for lifting said rollers above the level of the form.These lifting-plates are slotted, as shown at 6 in dotted lines in Figs.1 and 4, to receive pins 7, which so attach them to the roller-stands asto permit them to move upward and downward there- The saidlifting-plates are supported near each end on the lower parts of thestands by toggles n, and the toggles of each plate are connected attheir joints by a rod 0. 5 The lower member of one of said togglesbelonging to each lifting-plate is extended in the form of anelbow-lever, as shown at 8 in Figs. 1, 3, and 4t, and the said lever isconnected by a rod 19 with the stand top D on the corresponding side ofthe machine. When the stand-tops are down in their normal position,(shown in Fig. 1,) the toggles are so bent that they hold down thelifting-plates E in a position to allow the form-roller journals 7) torun in their bearings a; but when the stand-tops are lifted, as shown inFig. 4, the flexure of the toggles is reduced by the action of the rods0 and levers 8, and the lifting-plates E are caused to rise and lift theform-rollers 1) sufficient to clear the forms yet to leave theirjournals 1) within their bearings, so that on the return of thestandtops the rollers will drop to their normal positions.

While the printing-machine is in or in condition for operation the pawlm may be thrown back, as shown in Fig. 1, leaving the ratchet-wheel onfree, though the said pawl may remain in engagement with the saidratchet-wheel but the stand-tops are locked down by the engagement ofthe pawl j with the ratchet-teeth j When the stand-tops are to belifted, the pawl m must be in engagement, and the pawl j is thrown outof engagement by the attendant, who then turns the hand-wheel Z in thedirection of the arrow shown near it in Fig. 1 until the ratchetteeth 9'pass the said pawl, which may then be allowed to drop to the flange 7'of the wheel jand rest thereon while the attendant continues to turn thehand-wheel until the standtops are raised to the height desired, wherethey are locked by the pawl m, as shown in Fig. 4. When the stand-topsare to be lowered to bring the rollers d e to their operative position,the pawl m is thrown out of engagement and the stand-tops and rollerswill drop of their own weight, the said dropping being controlled so asto take place gently by the attendant, who exercises a slightholding-back action of the hand-wheel. The relocking of the stand-topsin the position last mentioned is effected by the arrival of theratchet-teeth j in engagement with the pawlj. The lifting and loweringmovement of the stand-tops will, as has been before explained, effectthe simultaneous raising and lowering movements of the formrollers.

What I claim as my invention is- 1. In the inking apparatus of aprintingmachine, the combination with roller-stand tops and supports towhich they are hinged, of toothed sector-carrying levers one on eachstand-top, a lifting-shaft and bearings therefor, pinions on said shaftone for each sectorcarrying lever, and means for turning and lockingsaid shaft, substantially as herein described.

2. In the inking apparatus of a printingmachine, the combination withroller-stand tops and supports to which they are hinged, of toothedsector-carrying levers one on each stand-top, a lifting-shaft andbearings therefor, pinions on said shaft one for each sectorcarryinglever, a gear on said lifting-shaft, a hand-wheel and a pivotal supporttherefor, gearing between said hand-wheel and said gear on thelifting-shaft for lifting the standtops, a ratchet on said gear and apawl engaging therewith for locking the stand-tops with their rollers inoperative position, a ratchet-wheel carried by said hand-wheel, and apawl engaging with the latter ratchetwheel to lock the roller-stands intheir lifted position, substantially as herein described.

3. In the inking apparatus of a printingmachine, the combination withfixed roller stands and inking-rollers and bearings therefor in saidstands, of roller-stand tops one for each side of the machine containingthe bearings for ink-distributing rollers, fixed supports to which saidstand-tops are directly pivoted at fixed points, lifting-plates appliedwithin said stands under the journals at both ends of the form-rollers,and connections between each so-pivoted stand-top and the lifting-plateon the same side of the machine for operating said lifting-plates by theraising of the stand-tops, substantially as herein described.

4. In the inking apparatus of a printingmachine, the combination withroller-stands and inking-rollers and bearings therefor in said stands,of roller-stand tops containing inkdistributing rollers, fixed supportsto which said stand-tops are directly pivoted at fixed points,lifting-plates applied within said roller-stands under the journals ofthe inking-rollers, toggles supporting said liftingplates, means forraising said stand-tops on their hinges and connections between saidsopivoted stand-tops and toggles for operating said lifting-plates bythe raising of the standtops, substantially as herein described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 28th day of October, A. D.1901.
